Just book it! Highly recommended. I've already recommended the place to my friends looking to stay in Bangkok.
Phil's place was like a home away from home. He was very quick to answer any questions I might have via text or phone call. His maid was delightful and made sure we had a comfortable stay. I had come to this place after touring Europe for 30 days and I had A LOT of laundry. She basically took care of everything for me including hanging out the laundry to dry. I tried to take care of it myself or even help but she was too sweet and too quick. Lol. After check out, we were able to leave our luggage and go around the city some more before our train departed.
